HUAWEI K3765 and Fonera 2.0N

Recently my ISP has been acting up, so I decided to setup a “backup” Internet connection that I can activate by simply plugging a USB stick into my Fonera 2.0N router.

Unfortunately my HUAWEI K3765 3G modem is not compatible with Fonera 2.0N wifi router out of the box, at least not with the current stable version of the firmware ( aka Gari the Hummingbird).

Here is what I had to do to make the USB modem work with Fonera 2.0N:

  • for some crazy reason, my 3G modem refuses to work on Fonera 2.0N if there are some SMS stored on it. Plug the 3G modem into your PC and remove any SMS you may have received. YMMV.
  • upgrade your Fonera 2.0N to the latest firmware, choosing the “developer” image. You need the developer version to ssh into your Fonera 2.0N.
  • ssh into your Fonera 2.0N router.
  • edit /etc/config/umtsd:

  • plug the HUAWEI K3765 into the Fonera 2.0N router
  • wait a few seconds and then run:

Visit http://fonera/luci/fon_devices/fon_umts and check the status of your 3G modem.

If it still doesn’t work, you may have to follow the instructions provided by stex1967:

Create the file /etc/usb-modeswitch.conf with the following content:

DefaultVendor= 0x12d1
DefaultProduct= 0x1520
TargetVendor= 0x12d1

Also create the file /etc/rc.d/k3765:

#!/bin/sh /etc/rc.common
sleep $sec
echo "0x12d1 0x1465" >/sys/bus/usb-serial/drivers/option1/new_id

Finally run:

chmod 755 /etc/init.d/k3765
/etc/init.d/k3765 enable

and reboot. Thumbs up!

Vodafone Mobile Connect: HUAWEI K3765

I recently purchased a HUAWEI K3765 HSDPA modem with Vodafone brand. It’s possible to use to this USB stick with any operator, by simply downloading the Mobile Connect software from HUAWEI (just google for it).

There is no need to flash a new firmware on it, just uninstall the Vodafone Mobile Connect software and replace it with the standard one from HUAWEI: you will be able to configure the software to use any APN you like.

You’ll still experience a small glitch though, at least under MacOSX: everytime you plug the modem into the USB port, you will see a popup asking you to install Vodafone Mobile Connect.

There is a simple solution to this problem:

  • find out the UUID of your USB stick: diskutil info /Volumes/Vodafone\ Mobile\ Broadband/ | grep UUID
  • create a new entry for this disk in /etc/fstab with the noauto flag turned on:
    • open /etc/fstab in your favourite editor (create it if it doesn’t exist yet): sudo vi /etc/fstab
    • add a line like the following to /etc/fstab:
      UUID=A46AA80A-97B9-3B47-91A4-8128A9458A31 none hfs rw,noauto 0 0

Replace the UUID with your own UUID.

Thumbs up! Now unplug your USB stick and plug it again: no annoying popup this time!


Upgrading firmware of Panasonic Lumix DMC-FT1

In short:

Panasonic has released a new firmware for the Panasonic Lumix DMC-FT1 compact camera which is worse than the previous version. The previous version (1.1) is no longer available on Panasonic website, so I made it available for you on my website:

Long story:

I already talked about the Panasonic Lumix FT1 camera in another post, in short the strenghts of this camera are:

  • ability to go under water
  • HD quality movies (720p)
  • optical zoom during movie recording
  • no limit on movie length

It’s really worth its price. You can find many example videos made with this camera on YouTube. The latest firmware available from Panasonic is ver. 1.2 . The main difference with regards to ver 1.1 according to Panasonic website is an “improvement of battery detection for safety standards Panasonic uses” which seems cool until you dig around for a while and discover that this improvement actually means that “after this firmware update your Panasonic Digital Camera cannot be operated by unauthorised 3rd party batteries“.
Wait a second, and you call this an improvement? No, thanks. I’d rather keep the ability to use 3rd party batteries.

So the next thing you do is check what other improvements have been introduced in firmware 1.1 compared to 1.0, here they are:

  • Capable of playing back AVCHD motion picture format (1,280 x 720 )
  • The quality of viewing image(still image) is improved.

Don’t care too much about the former, but the latter looks quite important.

Right, next question is: where can I download firmware 1.1 ? Panasonic was such nice to remove it from their website, and force anybody who wants to fix the 2 issues listed above to upgrade to ver. 1.2 and (bonus!) lose the ability to use 3rd party batteries.

That’s not nice, Panasonic!

Fortunately for you, I had the luck to save a copy of firmware 1.1 while it was still available, here it is for your convenience:
